AXLE-SET.

SPECIFICATION forming part of Letters Patent No. 429,245, dated June 3, 1890.

Application filed January 2'7, 1890- Serial No. 333,284 (No model.)

To aZZ whom it may concern:

Be it known that I, WILLARD F. NIGHTIN- GALE, a citizen of the United States, residing at Latrobe, El Dorado county, State of California, have invented an Improvement in Axle-Sets; and I hereby declare the following to be a full, clear, and exact description of the same.

My invent-ion relates to the class of axle sets or gages; and it consists in the novel constructions and combinations of parts hereinafter fully described, and specifically pointed out in the claims.

The object of my invention is to provide a simple and readily-operated tool or implement of this class which will accurately determine the set and gather of the axle-spindle.

Referring to the accompanying drawings for a more complete explanation of my invention, Figure 1 is a perspective view of my axle-set. Fig. 2 is a view from the other side. Fig. 3 is an end view. Fig.4 is a view showing the application of my axle-set.

The implement consists of a main or body bar A, which is approximately the length of.

an axle. To one side of this bar, at the point represented by a, is pivoted the gage-bar B, which has secured to its outer end, beyond its pivotal center, the gage-strip O.

D is an adjusting-screw, which is seated in a nuta' on the side of the guide-bar A, and has its ends journaled or connected with the end of the pivoted gage-bar B, whereby said bar is moved up or down to change its inclination to the body-bar A.

Fitted and adapted to slide back and forth upon the inner end of the gage-bar B is an indicator E, the position of which on the bar is regulated by the graduations or marks 1) upon the edge of said bar. This indicator E has on one side of it the graduations or marks e. Pivoted at f to the other side of the bodybar is a bar F, which is connected with the gage-bar B by a strap f, which passes over the body-bar A and connects said bars F and B. Pivoted at g to the bar F is an adjustable gage-strip G, having its other end slotted and passing over a set-screw g, whereby said stripmay be changed to different inclinations by loosening the set-scre\v, and set at any inclination desired by tightening up said screw. The desired inclination is determined by-a series of marks or graduations g on one end of the strip G, which compare with the series of graduations on the end of the bar F. Upon the other end of the body-barAis an adj ustable sliding arm-rest H. v

The point f, where the bar F is pivoted to bar A, is at the end, and said bar extends as far forward of the point of pivot a of gagebarB as the pivot-point f is back of a. Therefore the bar F, being connected at its end by strap f to bar B, is moved with said bar; but on account of the difference of location of their pivots and their relative positions the bar F is only moved to half the inclination of bar B.

The use of theimplement is as follows: In order to set it to the proper places to determine first the set of the spindle, so that the wheel may ride on a plumb spoke, I first determine by actual measurement the dish of the wheel. From this dish I subtract onehalf of the taper of the spindle and then find half the diameter of the wheel. I thereupon run the indicator E out on the gagebar to the mark or graduation representing half the diameter of the wheel, and then I turn the adjusting-screw D, so as to swing the gage-bar with relation to the body-bar until, aocordingto the gradnations on the side .of the indicator, the amount of the dish,

less half the taper of the spindle, is shown. This will give the required inclination of the gage-strip O. For example, if the dish of the wheel be five-eighths of an inch and one-half of the taper of the spindle be one-eighth, I thereupon have one-half for the dish, and if the half of the diameter of the wheel be two feet I thereupon run the indicator E out to the mark representing two feet and turn the gage-bar on its pivotal center until it shows I the one-half on the side of E. Now to apply the implement to the axle I run the arm-rest II out until it comes about opposite the collar of the axle. I then rest the arm-rest on one en d of the axle, and the angle which the gagestrip 0 forms with the spindle on the other end of the axle gives the gage or set for said spindle, so that it must be bent to the same inclination as the strip. To provide for the gather of the wheel, I take half the taper of the spindle and set the gage-strip G accordingly and then place it against the front of the spindle and bend said spindle to said strip. This will give the true gather, for the dish of the particular wheel is provided for by the connection of the bar F, which carries the gage-strip G, with the swinging gage-bar B, which latter, in providing for the set. as heretofore explained, also provides for the proper position of bar F, so that then half the taper of the spindle will give the true gather.

Iavin g thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In an axle-set, the combination of the body-bar, the swinging gage-bar pi voted thereto, by which the set of the spindle is determined, the gage-strip G, pivoted at one side and having its opposite side slotted and held by a set-screw, and the independently-pivoted bar, to which the gage-strip Gis pivoted, sub- 1 stantially as described.

2. In an axle-sot, the combination of the bod y-bar, the swinging gage-bar pivoted thereto, and by which the set of the spindle is de termined, the bar F, pivoted independently to the body-bar and connected with and moved by the gage-bar, and the adjustable gagestrip G on said bar F for determining the gather, substantially as herein described.

tion of the body-bar, the swinging graduated a. An axle-set consisting of the eombinagage-bar pivoted thereto, the gage-strip upon one end of said bar, the adjusting-screw at its other end, the sliding graduated indicator on said bar, the bar F, pivoted independently to the body-bar and connected With the swingmg gage-bar, the gage-strip G, pivoted at one end to the bar F and slotted at the other end, and the setscrew passing through said slotted end, substantially as herein described.

In witness whereof I have hereunto set my 40
